Explain what would happen to the food chains if: a.) A toxin was released into the local water supply, and the mice in the meadow died.

b.) There was an increase in the hawk population.

a. The hawks would die because the mice died, since the bottom part of the food chain was taken out, the whole food chain would fall apart;

b. All the mice would die; since there are more hawks to eat the mice, the mice would be eaten faster than they could reproduce, and they would slowly die out.

this website is for anybody really not just for girls just saying, also while a lot of males are mean and you know there are the few who are kind and then there's the nice-guys but then theirs also guys like me who are shy we don't get out much because there are people like you who exist who would most likely punch a guy in the face so next time just think about things before you post them to a website where guys and girls can see your question.
